Hello,
I recently came across a Samsung Galaxy A13 image.
It looks like the image has a trailer data shows as Hex values:
   0x00, 0x00, 0x01, 0x0A, 0x0E, 0x00, 0x00, 0x00, 0x49, 0x6D, 0x61, 0x67,
0x65, 0x5F, 0x55, 0x54, 0x43, 0x5F, 0x44, 0x61, 0x74, 0x61, 0x31, 0x36,
0x39, 0x35, 0x34, 0x38, 0x33, 0x33, 0x39, 0x39, 0x39, 0x30, 0x38, 0x00,
0x00, 0x61, 0x0C, 0x18, 0x00, 0x00, 0x00, 0x43, 0x61, 0x6D, 0x65, 0x72,
0x61, 0x5F, 0x43, 0x61, 0x70, 0x74, 0x75, 0x72, 0x65, 0x5F, 0x4D, 0x6F,
0x64, 0x65, 0x5F, 0x49, 0x6E, 0x66, 0x6F, 0x31, 0x00, 0x00, 0x10, 0x09,
0x15, 0x00, 0x00, 0x00, 0x46, 0x72, 0x6F, 0x6E, 0x74, 0x5F, 0x43, 0x61,
0x6D, 0x5F, 0x53, 0x65, 0x6C, 0x66, 0x69, 0x65, 0x5F, 0x49, 0x6E, 0x66,
0x6F, 0x46, 0x72, 0x6F, 0x6E, 0x74, 0x5F, 0x43, 0x61, 0x6D, 0x5F, 0x53,
0x65, 0x6C, 0x66, 0x69, 0x65, 0x5F, 0x49, 0x6E, 0x66, 0x6F, 0x53, 0x45,
0x46, 0x48, 0x6B, 0x00, 0x00, 0x00, 0x03, 0x00, 0x00, 0x00, 0x00, 0x00,
0x01, 0x0A, 0x76, 0x00, 0x00, 0x00, 0x23, 0x00, 0x00, 0x00, 0x00, 0x00,
0x61, 0x0C, 0x53, 0x00, 0x00, 0x00, 0x21, 0x00, 0x00, 0x00, 0x00, 0x00,
0x10, 0x09, 0x32, 0x00, 0x00, 0x00, 0x32, 0x00, 0x00, 0x00, 0x30, 0x00,
0x00, 0x00, 0x53, 0x45, 0x46, 0x54

As I see it, it has those tags and values:
  • image_UTC_data: 1695483399908
  • camera_capture_mode_info: 1
  • front_cam_selfie_info: front_cam_selfie_infoSEFK (not sure about that one..)

Is there any documentation about this data format? how should I read that?
Also, there are some more "random" bytes that I can't figure out their meaning...

Thanks in advance  8)

ExifTool will process a Samsung trailer, but there is still a lot of unknown information.  To see more details, use the -v3 option when using exiftool to extract information from the file.
